Answer:
The equation to this problem is 2,249
Answer:

Step-by-step explanation:

Part A:
firs multiply 9 to 3x and minus 16, after that subtract 15 from -144, then add both side to 129, then subtract 6x from both side, at the end divide bothe side to 21, the answer is 5.
9(3x-16)+15=6x-24
27x-144+15 = 6x-24
27x-129 = 6x-24
27x = 6x -24 +129
27x = 6x +105
27x - 6x = 105
21x = 105
21x/21 = 105/21
x = 5
Answer:
(1, 4)
Step-by-step explanation:
y=x+3
y=3x+1
y=x+3
x+3=3x+1
x=3x-2
-2x=-2
x=1
y=1+3
y=4
Y - 2x ≤ -3y - 2x ≤ -3
y - 2x ≤ -3y - 2x
y + 3y - 2x + 2x ≤ 0
4y ≤ 0
y ≤ 0
-3y - 2x ≤ -3
-3(0) - 2x ≤ -3
-2x ≤ -3
x ≥ 3/2
One of the solutions to the inequality is (3/2, 0)
